Title: Heat-pump hot water supply device
Inventor: IMOTO TAKUMI
IPC: F24H1/00
Filed: 1982-03-17
Abstract: PURPOSE:To prevent heat from being dissipated from a hot water storing tank due to  natural convection, by a method wherein a solenoid valve provided in a water circuit  is opened when passing an electric current to a compressor for a refrigerating cycle  and a pump provided in the water circuit, in the titled hot water supply device wherein  a tank and a heat pump are integral with each other. CONSTITUTION:When a switch 21 is closed, te compressor 10 and the pump 17 are  operated, and the solenoid valve 14 is opened. As a result, the refrigerating cycle is  formed in which a refrigerant discharged from the compressor 10 is passed through a  refrigerant passage in a water heater 11, is passed sequentially through a decompressor 12 and a heat absorber 13, and is sucked into the compressor 10 again. On the other  hand, in a water circuit, water pumped up from the tank 16 by the pump 17 is passed  through a water passage in the water heater 11, and is returned into the tank 16 by passing through a valve 14. When water in the tank 16 is heated to a sufficiently high  temperature, the switch 21 is opened to stop the supply of the electric current to the  compressor 10 and the pump 17, and the valve 14 is closed. Since the valve 14 is closed in this heat-insulating stage, the heat in the tank 16 is prevented from being dissipated due to natural convection.

IPC: B41J35/28
Filed: 1989-02-23
Abstract: PURPOSE:To reduce transmission loss of a driving force and to reduce in size a drive source by composing the device of a gear provided in a carriage for transmitting power from the source to a rack, and a reflecting plate provided between the source and an ink ribbon cassette. CONSTITUTION:Power of a stepping motor 15 is transmitted to a rack 17 via gears 19a, 19b, and 19c. In this case, since the transmission loss of the power merely includes rotary friction losses of the gears 19a, 19b and 19c, and friction losses between the gears 19a and 19b, 19b and 19c, the 19a and the rack 17, the losses are much less than that for transmitting power through a belt, etc., and sufficient power can be obtained by a small-sized stepping motor 15. Since the radiation heat from the motor 15 is reflected by the operation of a reflecting plate 20 of a stainless thin plate, heat transfer from the motor 15 to the upper surface of a carriage 8 is only by heat conduction, and hence the upper surface of the carriage 8 is raised, for example, only to 50 deg.C.

Abstract: PURPOSE:To enable accurate weighing, by a method wherein a rotating section is arranged freely rotatably about a rotating shaft, a plurality of weighing devices are provided to be positioned about the rotating shaft and th rotating section is turned about the rotating shaft. CONSTITUTION:Each time a weighing hopper 30 reaches the article supply position (A) or (B), a detection pulse is generated to perform a computation for combination.

Otherwise, no articles are discharged. On the other hand, when the weighing hopper 30 which arrived at the article supply position (A) or (B) is empty, articles are supplied into the weighing hopper 30 manually. After each weighing hopper 30 turns by a specified angle, the subsequent hoppers 30 reach the article supply positions (A) and (B) respectively and the next detection pulse is generated. At this point, an analog weighing signal is converted into a digital weighing signal and read into a microcomputer to perform a computation for combination.

Filed: 1982-03-18
Abstract: PURPOSE:To make the handling easy, by preventing the sound output from being outputted to a speaker, even if a plug is plugged in any jack of plural stereo headphone jacks. CONSTITUTION:When plugs are not inserted to the 1st and the 2nd headphone jacks 12L, 12R, the sound output of amplifiers 10L, 10R are given to ground through speakers 11L, 11R respectively. When the plug is inserted to the jack 12L only, the sound output of the left amplifier 10L is given to ground through a resistor R1, a terminal 3, a left speaker of a headphone and a terminal 7. Since a switch between the terminals 1 and 2 is opened, no sound output is given to the left speaker 11L. This is the same as the right amplifier 10R. When the plug is inserted to the jack 12R only, this is the case for the said jack 12L. When no plug is inserted to both the jacks, the sound output of the left amplifier 10L is outputted to the left headphone but no sound output is obtained from the speaker 11L, since the terminals 1, 2 and 1', 2' are opened. This is the same for the sound output of the right amplifier 10R.
